This function copies the results of the input method composition to composed_input_buf. Then for each character, a custom event of type wc_atom is sent with the character as its data. It is probably more efficient to copy the composition results to some allocated memory and send a single event pointing to that memory. That would cut down on the event processing as well as allow quick insertion into the buffer of the whole string. It might require some care, though, to avoid fragmenting memory through the allocation and freeing of many small chunks.
